we need to reach a point where we interact with computers of all types in the same way they do in star trek, i.e. natural voice with understandings of complex commands and language syntax

...and a static GUI with very limited number of poorly differentiated touch-buttons, complex arbitrary combinations of which give you any desired action? Also, exploding when there's something wrong at the nearest city block transformer?

WRT integrating an AI into the society... I cringe what kind of "moral values" we'll try to impose on it, the same way many humans try to do with other humans - while insisting on some silly superficialities, we might miss some really crucial ones, Asimov-style crucial*.
Because, see, since you focus on "emergent" AI - we have to take into account that the "true AI" might be, at the least, damn horny towards humans in some convoluted way (what with all the internet porn and viagra spam floating around).

* But his books might also seem a bit naive - around the time of their writing, we already had robots dedicated to killing humans, ICBMs being the most ultimate example (some even largely autonomously, like the Russian Perimetr aka Dead Hand system)
